When the popup window is translucently displayed, the data of the displayed application overlapping with the popup window is translucently displayed. When the popup window is opaquely displayed, data of the displayed application corresponding to an area of the displayed popup window is displayed in the remaining area other than the area without overlapping with the area. The controller 110 may display the data of the displayed application corresponding to the area of the displayed popup window in an area other than the area where the popup window is displayed. When receiving the command to enlarge the size of the popup window, the controller 110 may include additional information of a user having transmitted the event in the enlarged popup window. The controller 110 may include information basically provided corresponding to the received event (e.g., at least one of a sender's name, a sender's phone number, a reception menu, a speaker menu, a rejection message menu, and a rejection menu) and the user's additional information in the enlarged popup window. The additional information includes a sender's personal information (e.g., a sender's birthday, information on a schedule by appointment with a sender, and the like). When the event is received from the sender, the user may be reminded of memories for the sender. The controller 110 may include at least one piece of information in the popup window in correspondence to the enlargement of the popup window. The event may be any one of a voice call, a video call and text reception.

A controller 110 according to another embodiment of the present invention displays an executed application on the screen 120, generates a popup window including at least one piece of information in response to reception of an event, and displays the generated popup window on the displayed application. As described above, 25 the controller 110 simultaneously display the executed application and the popup window on the screen 120. The controller 110 may opaquely or translucently display the popup window on the screen 120 by controlling an attribute of the popup window. The controller 110 may display the popup window such that the popup window overlaps with the executed application, or may display data included in the executed application by moving the data to a location where the data does not overlap with the popup window. The controller 110 may change an attribute of the popup window in response to at least one command for size enlargement, size reduction, and location movement of the popup window, and may superpose and display the attribute changed popup window on the displayed application.

The controller 110 detects at least one command of a touch and a hovering event input for the size enlargement or reduction of the popup window and enlarges or reduces the size of the popup window to a location where the input is completed. The controller 110 adjusts information to be displayed in the enlarged or reduced popup window and displays the adjusted information in the popup window. Further, the controller 110 controls the screen 120 such that data of the displayed application corresponding to an area of the enlarged or reduced popup window is opaquely or translucently displayed. If the command corresponds to a command to enlarge the size of the popup window, the controller 110 enlarges the popup window and includes information contained in the popup window displayed on the screen 120 and additional information of a user having transmitted the event in the enlarged popup window. The controller 110 adjusts a display location of the data included in the displayed application in response to the movement of the popup window. Further, the controller 110 may translucently or opaquely change an attribute of the popup window, and the display location of the data may be determined according to the translucency or opacity of the popup window. When the popup window is translucent, the display location of the data may not be changed and the data may be displayed in a translucent status. Further, when the popup window is opaque, the data may be displayed below the popup window. The application includes an application for displaying a text, and the event includes a voice call.

Further, when reception of an event is detected in a state where at least one application is displayed on the screen 120, a controller 110 according to another embodiment of the present disclosure generates a popup window including at least one piece of information corresponding to the received event and displays the generated popup window on the displayed application. The event may include at least one of a voice call, a video call and a text message. The application may include an application capable of displaying a text such as news. If the received event corresponds to a voice call and a command to perform the voice call through a speaker is input, the controller 110 removes the displayed popup window and performs the voice call while displaying the application. When a command to perform the call through a speaker is input in the various telephone call methods, the controller 110 may terminate or remove the displayed popup window and perform the call while displaying the application shortly before the reception of the event on the screen 120.

When detecting an input by a touch or a hovering event at an arbitrary point on the displayed application, the controller 110 displays the generated popup window at a point other than the detected arbitrary point. A user inputs a command by using a touch or a hovering event on the displayed application. The command includes a command to select displayed data (e.g., in a case of a text, a command to select or copy a portion of the text). The controller 110 detects an input of the command and grasps a point where the command is input, while the application is displayed on the screen 120. The controller 110 may grasp a size of the generated popup window and display the generated popup window in an area other than the point where the input has been detected, so as to prevent the generated popup window from being displayed at the input detection point.

The controller 110 may display the popup window together with the application on the screen. The controller 110 may simultaneously display the popup window and the application on the screen 120. The controller 110 may translucently or opaquely display the popup window on the displayed application. The controller 110 may translucently display data of the displayed application corresponding to an area of the displayed popup window or may display the data in the remaining area other than the area of the popup window. Further, the data of the application corresponding to the area where the popup window is displayed may be hidden by the popup window, in which case the controller 110 may control at least one of the application and the screen 120 such that the data hidden by the display area of the popup window is displayed in the remaining area other than the area where the popup window is displayed. For example, the controller 110 may display the data of the application on an upper, lower, left, or right side of the popup window. When the displayed application corresponds to news or a newspaper article based on a text, the controller 110 extracts the displayed text and displays the extracted text on a lower, upper, left, or right side of the popup window. A display location of the text may be adaptively determined corresponding to at least one of location movement and size adjustment of the popup window. When the popup window is displayed while the application is being displayed, data of the displayed application corresponding to an area of the displayed popup window may be hidden, in which case the controller 110 may simultaneously display the popup window and the data in the same area, by adjusting transparency of the popup window and the corresponding data of the application hidden by the popup window to translucency. The transparency may be adjusted by the controller 110 to a degree that can be recognized by a user.

The controller 110 changes an attribute of at least one of the popup window and an area of the application corresponding to the area of the popup window in response to a command to control the popup window. The attribute of the displayed popup window may be changed by at least one of size enlargement, size reduction, and location movement. The attribute of the area of the application corresponding to the area of the popup window may be changed in correspondence to the changed attribute of the popup window. When the command corresponds to a command to enlarge a size of the popup window, the controller 110 enlarges the size of the popup window. In this case, the enlarged popup window may include information included in the popup window displayed corresponding to reception of an event and additional information of a user having transmitted the event. The additional information may include a sender's personal information (e.g., a sender's birthday, information on a schedule by appointment with a sender, and the like). When the event is received from the sender, the user may be reminded of memories for the sender, and the additional information may include information useful for reminding the user of the memories. As described above, the controller 110 may include at least one piece of information in the popup window in correspondence to the enlargement of the popup window.

The controller 110 may translucently display data of the displayed application corresponding to an area of the enlarged popup window or may display the data in the remaining area other than the area of the enlarged popup window. The controller 110 may translucently or opaquely display the enlarged and/or moved popup window on the displayed application. Further, the controller 110 may translucently display the data of the displayed application corresponding to the area of the enlarged and/or moved popup window or may display the data in the remaining area other than the area of the enlarged and/or moved popup window. Further, the data of the application corresponding to the area where the enlarged and/or moved popup window is displayed may be hidden by the popup window, in which case the controller 110 may control at least one of the application and the screen 120 such that the data hidden by the display area of the popup window is displayed in the remaining area other than the area where the enlarged and/or moved popup window is displayed. For example, the controller 110 may display the data of the application on an upper, lower, left, or right side of the enlarged and/or moved popup window. When the displayed application corresponds to news or a newspaper article based on a text, the controller 110 may extract the displayed text and may display the extracted text on a lower, upper, left, or right side of the popup window. A display location of the text may be adaptively determined corresponding to at least one of location movement and size adjustment of the popup window. The screen 120 receives at least one touch through a user's body (e.g., the fingers) or a touchable input unit (e.g., a stylus pen or an electronic pen). Further, the screen 120 includes the hovering recognition device 121 and the touch recognition device 122 which can properly recognize an input according to an input method when the input is made through a pen such as a stylus pen or an electronic pen. The hovering recognition device 121 may determine a distance between the pen and the screen 120 through a magnetic field, an ultrasonic wave, optical information, or a surface acoustic wave, and the touch recognition device 122 may detect a touched location by using electrical charge moved by a touch. The touch recognition device 122 may detect all touches that can generate static electricity and may also detect a touch by a finger or a pen which is an input unit. The screen 120 transmits an analog signal corresponding to at least one gesture to the screen controller 130.

In various embodiments of the present invention, the touch is not limited to contact between the screen 120 and a user's body or a touchable input unit, and may include non-contact (e.g., a detectable interval without the contact between the screen 120 and the user's body or the touchable input unit). The interval which can be detected by the screen 120 may be changed according to a capability or a structure of the electronic device 100, and, for example, the screen 120 is configured such that values detected by a touch event and a hovering event (e.g., including a voltage or current value as an analog value) may be differently output for separate detection of the touch event by the contact between the screen 120 and the user's body or the touchable input unit and the input event (e.g., the hovering event) in a contactless status. In addition, the screen 120 may differently output the detected value (e.g., a current value) according to a distance between a space where the hovering event is generated and the screen 120.

The hovering recognition device 121 or the touch recognition device 122 may be implemented, for example, in a resistive type, a capacitive type, an infrared type, or an acoustic wave type.

The hovering recognition device 121 is an ElectroMagnetic Resonance (EMR) type touch panel and may include an electromagnetic induction coil sensor having a grid structure in which a plurality of loop coils are arranged in a predetermined first direction and a second direction intersecting with the first direction and an electronic signal processor sequentially providing an alternating current signal having a predetermined frequency to each of the loop coils of the electromagnetic induction coil sensor. If an input unit including a resonance circuit therein exists in the vicinity of the loop coils of the hovering recognition device 121, a magnetic field transmitted from the corresponding loop coil generates a current based on mutual electromagnetic induction in the resonance circuit within the input unit. An induction magnetic field is generated, based on the current, from a coil that configures a resonance circuit within the input unit, the hovering recognition device 121 detects the induction magnetic field around the loop coil in a signal reception state to sense a hovering location or a touch location of the input unit and a height from the touch recognition device 122 to a pen point of the input unit.

The touch recognition device 122 is a capacitive touch panel in which a thin metal conductive material (e.g., an Indium Tin Oxide (ITO) film) is coated on opposite surfaces of glass such that a current flows on the glass surface and a dielectric substance capable of storing electrical charges is coated thereon. When the input unit (e.g., a user's finger or a pen) is touched on a surface of the touch recognition device 122, a predetermined amount of electric charge moves to a touched location due to static electricity, and the touch recognition device 122 detects the touched location through recognizing a variation in a current according to the movement of the electric charge. Through the touch recognition device 122, all touches that can generate static electricity may be detected and a touch by a finger or a pen which is an input unit may also be detected.

Further, the screen 120 may include at least two touch screen panels which can detect touches or approaches of the user's body and the touchable input unit in order to sequentially or simultaneously receive inputs by the user's body and the touchable input unit. The at least two touch screen panels provide different output values to the screen controller, and the screen controller may differently recognize the values input into the at least two touch screen panels to distinguish whether the input from the screen 120 is an input by the user's body or an input by the touchable input unit. The screen 120 may display at least one object or input text.

More specifically, the screen 120 may be formed in a structure in which a touch panel detecting an input by a finger or an input unit through a change in an induced electromotive force and a panel detecting contact of a finger or an input unit on the screen 120 are attached to each other or spaced apart from each other to be stacked in sequence. The screen 120 includes a plurality of pixels, and may display an image or handwriting input by an input unit or a finger through the pixels. The screen 120 may be a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED) display, or a Light Emitting Diode (LED) display.

Further, the screen 120 may include a plurality of sensors for determining a location of a finger or an input unit when the finger or the input unit contacts a surface of the screen 120 or is spaced a predetermined distance apart from the screen 120. Each of the plurality of sensors may be formed in a coil structure, and in a sensor layer formed of the plurality of sensors, the sensors may have preset patterns and may form a plurality of electrode lines. Due to the structure, when contact is generated on the screen 120 through a finger or an input unit, a detection signal of which a waveform is changed on account of capacity between the sensor layer and the input unit is generated, and the screen 120 may transmit the generated detection signal to the controller 10. The predetermined distance between the input unit and the hovering recognition device 121 may be determined through an intensity of a magnetic field formed by the coil.

The screen controller 130 converts an analog signal received by a text input to the screen 120 to a digital signal (e.g., X and Y coordinates), and transmits the digital signal to the controller 110. The controller 110 controls the screen 120 by using the digital signal received from the screen controller 130. For example, the controller 110 may allow a short-cut icon or an object displayed on the screen 120 to be selected or executed in response to a touch event or a hovering event. Further, the screen controller 130 may be included in the controller 110.

Further, the screen controller 130 identifies a distance between a space where a hovering event is generated and the screen 120 by detecting a value (e.g., a current value) output through the screen 120, and converts the identified distance value to a digital signal (e.g., a Z coordinate) to provide the digital signal to the controller 110.

FIG. 2 is a flowchart illustrating a method of controlling a screen of an electronic device according to an embodiment of the present invention.

A screen 120 displays a currently executed application, in step S210. The controller 110 displays the application selected or pre-designated by a user on the screen 120. The application includes predetermined data, and the predetermined data may be displayed on the screen 120. The predetermined data may be different according to a type of application. A location where the predetermined data is displayed may be adjusted by the controller 110.

When it is determined in step S212 that an event has been received, the controller 110 generates a popup window including information corresponding to the received event, in step S214. The event may include at least one of a voice call, a video call and a text message. The present invention may also be applied to a case of receiving an event irrespective of a user's intention while the user performs a task through the application, in addition to the voice call, the video call and the text message.

The generated popup window may include information on a user having transmitted the event. For example, as described above, when the event corresponds to the voice call, the information included in the generated popup window may include at least one of a sender's name, a sender's phone number, a reception menu for starting the call, a speaker menu for starting the call through a speaker, a rejection message menu for transmitting a message to a sender to inform of a status of not receiving the call, and a rejecting menu for rejecting the call. When the event corresponds to the text message, the information included in the popup window may include at least one of a sender's name, a sender's photo, a sender's phone number, a reply menu for transmitting a reply to the received text, a view menu for viewing the received text, a deletion menu for deleting the received text, and a cancel menu for viewing the received text later.

As described above, an attribute of the generated popup window may be changed in response to at least one command of size enlargement, size reduction, and location movement. When the command corresponds to a command to enlarge a size of the popup window, the controller 110 may enlarge the size of the popup window and may include, in the enlarged popup window, personal information (e.g., a sender's birthday, information on a schedule by appointment with the sender, and the like) of the user having transmitted the event as well as the aforementioned information basically provided. When the event is received from the sender, the user of an electronic device 100 may be reminded of a memory for the sender through the additional information. When the command corresponds to a command to move a location of the popup window, the controller 110 may move the location of the popup window.

The controller 110 displays the popup window generated in step S214 on the executed application, in step S216. As described, above, the controller 110 displays the generated popup window on an upper layer or a lower layer of the currently executed application while the popup window overlaps the application. The controller 110 may display the currently executed application and the generated popup window simultaneously or all together on the screen 120. The controller 110 may translucently or opaquely display the popup window on the displayed application. Further, the controller 110 may translucently display the data of the displayed application which may be hidden by the displayed popup window, or may display the data in the remaining area other than an area of the popup window. As described above, the controller 110 may adjust the display location of the data of the displayed application corresponding to the popup window. For example, when the popup window is opaquely displayed, the controller 110 may display the data of the displayed application corresponding to the area of the displayed popup window in the remaining area other than the area of the popup window.

FIG. 3 is a flowchart illustrating a method of controlling a screen of an electronic device according to another embodiment of the present disclosure.

A screen 120 displays a currently executed application, in step S310. A controller 110 displays an application selected or pre-designated by a user on the screen 120. The application includes predetermined data, and the predetermined data may be displayed on the screen 120. A location where the predetermined data is displayed may be adjusted by the controller 110. The application may include a text based application.

The controller 110 displays a popup window including information corresponding to the received event on the screen 120, in step S312. The event may include at least one of a voice call, a video call and a text message. The information included in the popup window may be different according to a type of event. The controller 110 may simultaneously display the application and the popup window on the screen 120. Further, the controller 110 may display the popup window on the application while the popup window overlaps the application. The controller 110 may translucently display the popup window on the application, or may translucently display the data of the application corresponding to an area where the popup window is displayed. Further, the controller 110 may opaquely display the popup window on the application, and at this time, may display the data of the application corresponding to the area of the opaquely displayed popup window in the remaining area other than the area of the popup window. The controller 110 may display the data of the application on an upper, lower, left, or right side of the popup window. The location where the data of the application is displayed may be changed according to translucency or opacity of the popup window.

When it is determined in step S314 that a command to change an attribute of the popup window has been input, the controller 110 changes an attribute of at least one of the popup window and the area of the application corresponding to the popup window of which the attribute is to be changed and displays the popup window and the application in response to the input command, in step S316. The command may include at least one of size enlargement, size reduction, and location movement. Further, the command may include a command to allow the opaquely displayed popup window to be translucently or transparently displayed. At least two of the size enlargement, the size reduction, and the location movement may be simultaneously performed. The controller 110 may change the attribute of the displayed popup window and may change the attribute of the application in correspondence to the changed attribute of the popup window, when the command is input. The controller 110 may change an attribute of at least one of the popup window and the area of the application corresponding to the area of the popup window in response to a command to control the attribute of the popup window.

If the command corresponds to a command to enlarge a size of the popup window, the controller 110 enlarges the size of the popup window. Further, the controller 110 may include, in the enlarged popup window, at least one piece of information included in the popup window displayed in step S312 and additional information of a user having transmitted the event. The additional information may differ according to the received event. The additional information may include a sender's personal information (e.g., a sender's birthday, information on a schedule by appointment with a sender, and the like). For example, when the received event corresponds to a voice call, the additional information may include information stored by a user, such as a date and time when the latest call has been made and a date, time, and a place for meeting by appointment with the user having transmitted the event. Further, when the received event corresponds to a text message, the additional information may include information stored by the user, such as contents of a recently transmitted/received text and a date, time, and a place for meeting by appointment with the user having transmitted the event. The controller 110 may extract the information on the user having transmitted the event from a storage unit 170 in response to the received event, and may generate and display the popup window. The additional information may include information to help the user be reminded of a memory for the user having transmitted the event in response to the event reception.

The controller 110 may translucently display data of the application corresponding to an area of the enlarged popup window or may display the data in the remaining area other than the area of the enlarged popup window. If the command corresponds to a command to move a location of the popup window, the controller 110 moves the location of the popup window, and translucently displays data of the displayed application corresponding to an area of the moved popup window, or displays the data in the remaining area other than the area of the moved popup window.

When the event received in step S312 corresponds to a voice call and a command to perform the voice call through a speaker is input, the controller 110 may cancel or remove the displayed popup window and may perform the voice call while displaying the application. In this case, the displayed application may provide, to the user, various functions that may be performed before the user receives the voice call. Further, when an input by at least one of a touch and hovering at an arbitrary point on the displayed application is detected, the controller 110 displays the popup window displayed in response to the event reception at another point or area other than the arbitrary point.
